'Qonner,Grand Rapids, Mich. ,2 Application June 8, 1933, Serial No, 674,791claims; (01.112-158) The present invention relates tosewing machines;and its object is, generally, toprovide an improved device'fon sewing.fasteners; such as buttons and thelike'jon garments, or other bases;

5 and more particularly, to provide improved mechanism' for oscillatingthe needlesof such a machine sidewise so as to pass alternately throughspaced: holes in the fastener; and further, to provide saidmechanismmountedion' sewing machine parts of usual type; and further, toprovide said mechanism adapted to formv embroidery stitching and buttonhole stitching on such a fabric'or base.

These and any other and more specific objects 15, hereinafter appearingare attainedby; and the invention finds preferable embodiment in, *the'device, including said mechanism, particularly described in the body ofthis-"specificationand illustrated by the accompanying drawings, in 20which: 7 I r Figure 1 isa view in perspective of portions :of a sewingmachine with my device applied thereto;

In the embodiment of the invention illus-[ trated by these drawings, mydevice is shown detachably applied to a sewing machine of or-, 5 dinarytype having the table or work support i and the horizontal arm 2extending thereover in whose head 3 the vertically movable bar '4carrying the usual detachable presser foot is slidable and theneedle-carrying bar 5 reciprol0 cates in the sewing operation, usualthread-ten sioning means 6 and I being indicated in Figure 1. "I I Mydevice comprises suitable means for positioning-i, e., moving andholding in moved position--the fasteners in proper location on thefabric or base 9 to which they are to be sewed, and comprises alsomechanism for oscillatingsidewise the needle iii of thesewingmachine soas to pass alternately through a pair of spaced holes in said fasteners.

The means for thus positioning such fasteners, as the flat buttons 8, 8is particularly well shown in, Figure2 and is detachably mounted on saidbar 4 (after removing therefrom the usual presser'foot), the deviceincluding a; plate having a horizontal portionor flange i3 with a notchl4 receiving the flattened portion IE5 or bar 4, this flange beingclamped betweensaid 30 threaded on this bar. On this'fiange I 3 is piveoted at l8 a lever 'arm l9 having an operating handle portion 2!! and arecess with angularly disposed sides 2| adapted to receive and hold thebutton 8 or 8 the button being yieldingly' 35, pressed into such holdingengagement with the sides 2! by a spring 22. This spring has an inwardlyextending flange or edge portion 23, engaging the under side of thebutton, while said sides 21 have grooves 24 receiving the opposite edgeof the button to hold the same in place in the lever arm i9, this arm(when lowered by the usual means for loweringand raising the presserfoot bar of such machines) serving asapresser foot to hold the button inproper relation to the fabric 9 on the plate 25 of; the machines table,below which plate the shuttle '(not shown) operates. The degree to whichthis lever arm l9 may be turned on pivot I8 is limited by adjustablestops, the screws 26 threaded in'the arm, which stops are engaged by therearward extension 21'of the fiange l3. In sewing buttons 8 having onepair of holes H H as shown in Figure l,the arm lfl'of said positioningmeans is turned to a position wherein the button is held with its holesaligned in the direction of the needles oscillation (hereinafterexplained) and the arm is fastened in said position by the screws 26,and in the sewing operation the needle passes through these holes 7alternately; but in sewing buttons 8 having two 7 "pairs of holes H, Hand I2, I2 as shown in Figures 2 and 3, the arm i9 is turned, (thescrews adjacent end of said plate. The lever '35 and I 'I'heneedle l0iscarried by plate turning of said plate on its pivotal mounting 34 26being adjusted to proper limiting position), say first to the right hand(as seen insaid views) -'so that the button 8 is held with its holes II,

' H aligned as aforesaid, whereupon the needle in its oscillation passesthrough these holes alternately; this done, the arm leis turned towardthe leftghand thus aligning the other pair of its holes, I2, I21,asaforesaid; and the needle passesthrough these two holes alternately.

The mechanism for thus oscillating the needle l0 includes: a membercarried by the needle bar 5 and having a body 28 which, in theparticular iconstruction shown, is made up of spaced side plates 29connected at their ends by cross bars or blocks 30 passing therethroughand threaded in the block 30; a needle carrier plate 33 on the'underside of said body and pivoted at 34 on the bottom of, block 3| so as toturn horizontally; and a lever 35 pivoted at 36 on the underslde ofplate 33 so as to turn horizontally, having one of its arms 31 bentupwardly and extending through a slot38 in the plate 33 andthence'beyondthe plate 33 are yieldingly held in parallel relation as seen'in Figure9 by a U-shaped spring 39 fastened in its middle at 40 on said plate andhaving arms 4| pressing on the opposite edges of the other'arm 42 of thelever.

oscillates the needle sidewise. The needle is thus carried by anysuitable means on the said plate,

preferably detachably as shown, as on a small mounting plateor block 43tightly fitting in a. socket 44 in plate 33 and held therein by anoverlying bar 45 having screws 46 extendingtherev through" and threadedinplate 33; The needle extends downwardly through a large opening 41 inthe lever 35: The movement of plate 33 on said body about the pivot '34is limited by ad-' .needle bar 5, as' on the upwardly-forwardly curvedarm or flange 5! of the 'plate 13 which is jmourited onthe presser bar4. On the right hand side (or inner side). of this arm 5| said member 53is pivoted at 52fa'nd is a triangularly'shaped plate or trigger havingupwardly diverging opposite sides 54, 55, along one-of which the. endportion 56 of lever 35 moves inthe movement of needle bar 5 in whichytheneedle passes through one of the holes of any pair thereof in the buttonfand along the other one of which sides said end portion movesin theneedles movement through the other hole of said pair. ,The needleoscillating mechanism operates in position preparatory and 3| saidbody-being detachably =mounted-on the needle bar by a set screw 32' r Vrearward hole of the button. 33 so that the a A leaf the followingmanner: Assuming now that the needle has justmade a stitch through thebuttons forward hole H I2 (Figure 2) or H (Figure 1) and is rising, theparts are in the following positions: The plate 33 is in forward swungposition, the lever 35 thereon is in its neutral or middle position seenin Figure 9, and the mom:- ber 53 is in the turned position seen inFigure 6.;

When the needle bar 5 rises far enough, the eii'd portion 56 of lever 35engages thelower portiqn of side 55 of member 53 thus turning'lever' 35frearwardly, i. e. to its position seen in Figure"- 8 (which is abottomplan view) and thereby swings plate 33 withit carrying the needleto rearward to next stitching through the buttons rearward hole II, I!(Figure 2) or m (Figure 1).

.When said end portion 56 in upward 'movement of the needle bar 5passesabove the pivot'52'of member 53, this end portionturnssaidmer'nber 53 toward the position seen inFigure 5 whereupon thismembers pin 51 (extending through slot 58 in flange 5|) tilts the spring59: (pivotedatfill on said flange) from. the positionseen in Figure .10and said spring suddenly urges said member to its oppositefpositlon;seenin Figure5..

The needlejbar now moving: downwardly and carryingsaid end portion 56 oflever '35 alongthe side55, of member 53..stitches through thebuttons'rearward hole H, l2" (Figure 2);or H (Figure 1).; and whensaidend portion 56 passes below the point. 6| of said member the spring 41is permitted to return lever-35 to its middle or neutral position seeninFigure 9, the plat'e33' however remaining in its rearwardly swungposition aforesaid to make the stitch through said The member 53 is nowin the turned position seen in Figure '7 so that, preparatory to making,the'stitch through the buttons forward hole H I2 (Figure 2) or H(Figure 1), the rlsingend portion 56 offlever 35 engages the other side54 of member 53 and the partsare operated sim-1 ilarly to, but reverselyfrom themanner above described in order to swing plate 33 forwardly,

etc.
